I went and looked, the complete box i have is definetly for a 48-50 F-1
The left fender is near immaculate, the right has three small dings in the top portion of the fender, not on the body seam or line. should be an easy repair. was planning on using them on my 51 until i learned they were different.

I didn't get your e-mail. possibly deleted it by accident.
no problem seperating the fenders. the bed isn't the best anyways and
with you it would be too much to attempt to ship across the country.
Not sure what to ask for the fenders. i'll be down there again this weekend, will take pics so i can e-mail them to whom'ever would like to see them.
